Product Features

Feature 1 :Adjustment Screws can be used to adjust the the workpiece position slightly through the adjusting screw, so as to play the role of precise positioning.
Feature 2 :The overall heat treatment (HRC35~42) has reduced abrasion caused by contact with workpiece.
Feature 3 :Unlike a flat end bolt, the front end round head makes point contact with the workpiece, thus absorbing the inclination of the tapped hole.
Feature 4 :Adjustment Screws coarse or fine thread pitch is available. Choose the fine thread type when slight adjustment is required.
Feature 5 :A nut for fixing the Adjustment Screws is included. Therefore, it can be fixed after purchasing the adjusting screw components.

Usage Method

Product Drawings	Detailed Description about Adjustment Screws usage
	Due to the Adjustment Screws use of a front end round head shape, it can absorb the eccentricity caused by the inclination of thread processing. Therefore, only one point can be used as a support for positioning.
	Adjustment Screws has overall heat treatment, there is little wear even after repeated contact caused by collision during positioning.
	Using Adjustment Screws two adjustment bolts simultaneously on one side of the workpiece can easily achieve lateral positioning.
	Adjusting screw front end is quenched. If it is necessary to avoid damaging the workpiece during positioning, it is recommended to use it in conjunction with theset pin.
